CAPONORD 1200
•
too high/too low
Error cause
•
If too high: too high a voltage has been detected at PIN 42. If too low: too low a voltage has
been detected at PIN 42. The instrument panel does not indicate the presence of this error
even in the ATT status.
Troubleshooting
•
If too high: check correct operation of the voltage regulator.
•
If too low: check voltage regulator connectors, engine - vehicle cable harness connector and
the control unit connector (paying special attention to possible oxidation): if not OK, restore;
if OK, check that Red/White cable resistance from the voltage regulator connector to the
control unit connector is a few tenths of Ohm: if not OK, restore cable harness; if OK, check
correct operation of the electrical alternator: if not OK, restore; if OK, check operation of the
voltage regulator
